How to Rationalize the Denomonator in Surds

In order to rationalize the denominator, we need to get rid of all radicals that are in the denominator.
Step 1: Multiply numerator and denominator by a conjugate of the denominator.
Step 2: Make sure all radicals are simplified.
Step 3: Simplify the fraction if needed.

Nice work sir, for this very problem the time is not long enough.

[NgoziOnuekwusi]

Sir thanks I understood you correctly.

[BenardAsare-sj]

Am also confused a bit buh i like ur explanation

[favourokpalugo]

Am confuse, why didn’t you do denominator 2 root 5 * 1

[catherinekalunga]

Thank you sir
But why have you written root 25 there?

[amandaodo]

Please why did you add plus hen rationalizing

[ousmanjallow]

Why you don't maintain the negative sign?

[favourokpalugo]

How did you get 4 root 5🤦‍♀️ I thought the 4 is meant to be added to 10+2

√5 × 2√5 is 10 because √5 × √5 is 5 and 2×5 is 10

solve this problem


root5/root15_root10

[AaronWagubi]

U said a rational no multiplies a rational no and irrational no also multiplies an irrational no

[shanteraguyguy]

I thought 5 root by 5 root will give you 5
